Reconstruction of the Zubří sports hall in the Zlín Region

Zubří Sports Hall is a town sports hall with facilities, which is used by the primary school as well as by the public and local sports clubs mainly for sports activities, more rarely for cultural activities.
The hall was in poor energy condition: in the winter a large amount of heat was leaking through the perimeter structures, in the summer the building overheated, the existing old air conditioning equipment was not operated due to its high noise and cost. The 21-year-old system of nine gas boilers was already very faulty. The indoor microclimate was very poor and the heating and operating costs were unbearably high.
Therefore, the town Zubří decided on the complete reconstruction of the building. The perimeter walls of the building and the floor in the terrain are insulated with thermal insulation. New windows and doors are equipped with triple glazing. The old boilers were replaced by heat pumps and air conditioning with recuperation, which altogether ensure a healthy indoor microclimate and a comfortable stay in the hall for athletes and spectators. Last but not least, a new storage tank for solar water heating was also installed.
OP Environment of the Czech Rep. (2014 - 2020) supports the measures under Priority Axis 5, specific objective 5.1: To reduce the energy demand of public buildings and increase the use of renewable energy sources. Energy Agency of the Zlín Region participated in the project coordination and processed the application for a subsidy.

Total implementation costs: CZK 48.618,303 (app. 1.945.000 EUR)
OP Environment: CZK 10.373.799 (app. 414.950 EUR)
Zubří municipality: CZK 38,244,503 (app. 1.530.000)

• Reduction of energy consumption for heating by 860.38 GJ / year, which is a decrease of 40% compared to the state before implementation.
• Reduction of CO2 emissions by 50.02 t / year compared to the state before implementation
• Heating is provided by a cascade of five heat gas pumps with a total output of 187.5 kW, backup sources are two gas boilers with a total output of 94.2 kW
• Ventilation is provided by 5 air handling units with recuperation with a total air output of app. 22,50 m3/h

• Dealing with unpredictable changes of the project during construction: changes are addressed not only in terms of construction and finance, but also in terms of public procurement
• Methodical guidance of sports hall staff in monitoring consumption and processing energy management of the building

The Zubří Municipal Sports Hall is an example of a successful overall reconstruction, including a reduction in the energy demand of the building.
After the implementation, the costs of heating and operation have been significantly reduced, however, it is necessary to implement energy management - the methodological management of which is provided by Energy Agency of the Zlín Region.
Well-insulated insulation, replacement of the heat source and installation of HVAC with recuperation in the public sector building is important, as the general public as a user can know the transformation of the old building into a new one and learn more about the possibilities in the field of reconstruction.
Thanks to the financial support of the OP Environment , it is possible to implement such projects and thus increase the general public's interest in thermal insulation, replacement of heat sources and the use of HVAC with recuperation.
